The phrase "backward scattering" is correct and usable in written English.
It is most often used to refer to the scattering or diffusing of a physical wave (like a sound or light wave) in a direction opposite to that of the wave's movement. For example: "The sun's rays were scattered in a backward scattering pattern against the wall."
The parameter g varies between -1 and 1: g=0 corresponds to isotropic scattering (Rayleigh), g=1 to total forward scattering and g=−1 to total backward scattering.
This introduces the ideas of forward and backward scattering.
The present work shows a series of results of Deep Inelastic Neutron Scattering (DINS) experiments on light and heavy water mixtures performed at the spectrometer VESUVIO (Rutherford Appleton Laboratory, UK) employing an analysis method based on the information provided by individual detectors in forward and backward scattering positions.
Overall, we provide a flexible mean to gain enhanced total and forward scattering together with suppressed backward scattering.
As Δ j increases, lower impact parameters are required to excite the NO radicals, leading to a gradual change from forward scattering to side and backward scattering.
This means that for a spherical particle, whatever the particle parameters are, it is not possible to obtain much larger forward scattering by fulfilling the first Kerker's condition within dipole approximation for the minimum backward scattering.
It is also seen that the electric and magnetic dipolar resonances approach each other gradually with increasing a/b, which can allow obtaining minimum backward scattering at the resonance of total scattering.
In this paper, the scattering characteristics of the spherical and ellipsoidal dielectric nanoparticles have been investigated, in order to obtain enhanced total and forward scattering together with suppressed backward scattering.
From Fig. 5, it is seen that the electric and magnetic dipolar resonances approach each other gradually with increasing a/b, which can allow to obtain minimum backward scattering at the resonance of total scattering.
11 The forward and backward scattering from individual Au nanobump are observed above and below Au surface, respectively.
